ELECTROMECHANICAL COIN TOTALIZER Filed July 27, 1956 4 Sheets-Sheet 4Unite My invention relates to an electromechanical coin totalizer andmore particularly to an electromechanical coin totalizer for use withmerchandising machines for selectively dispensing a number of differentbrands or kinds of merchandise selling at various prices.

If the market demand is to be met, a merchandising machine must becapable of dispensing a number of kinds or brands of merchandise sellingat various respective prices. For example, if an improved machine isadequately to dispense packages of cigarettes, it must provide thecustomer with a choice of a great number of different types ofcigarettes, such as regular size, king size and filter-tip cigarettes ofvarious brands. It will be appreciated that the various kinds and brandsof cigarettes sell at diiferent respective prices. The price at which aparticular type or brand of cigarette is sold may be subject to change.These considerations are likewise true where a merchandising machine isto dispense other kinds of merchandise, such, for example, as variousbeverages selling at difierent prices. A coin totalizer for use in sucha machine must register the deposited sums of money and condition thedispensing means of the machine to operate in response to the deposit inthe totalizer of different respective sums in coins. Advantageously, thecoin totalizer should provide means by which the price of any article ofmerchandise dispensed by the machine may readily be adjusted within widelimits. It is desirable that a coin totalizer be adapted to make changein the event a customer does not have the exact change required topurchase an article of merchandise dispensed by the machine. Further,the coin totalizer should be simple in construction and reliable inoperation.

One object of my invention is to provide an electromechanical eointotalizer for use with a merchandising machine which dispenses differentkinds or brands of merchandise selling at various prices.

Another object of my invention is to pro-vide an electromechanical cointotalizer which permits ready adjustment of the price at which anarticle of merchandise is sold.

A further object of my invention is to provide an electromechanical cointotalizer which makes change.

A still further object of my invention is to provide anelectromechanical coin totalizer which is simple in construction andreliable in operation.

Other and further objects of my invention will appear from the followingdescription.

In general, my invention contemplates the provision of anelectromechanical coin totalizer including a totalizer switch and meansfor positioning the switch in response to the deposit in the totalizerof a sum in coins. To obtain an article of merchandise, a customer firstopcrates a selector switch of the machine with which my totalizer isused to condition the machine to dispense a selected beverage or articleof merchandise. Upon the deposit in the machine of a sum in coinsaggregating the purchase price of the selected article the selectorswitch and the totalizer switch automatically complete the circuit of adrive motor which closes a vend switch to complete the circuit of thedelivery solenoid associated with the selected beverage or article ofmerchandise. The totalizer switch reset means begins to reset thetotalizer switch when the motor is energized. A cam operated atent O icefollow-through switch bypasses the totalizer switch to maintain thedispensing and change-making circuits until one revolution of the motoris complete.

It is to be understood that the operation of the ma chine may beinitiated by conventional push buttons. As is common in the art, I mayprovide one push button associated with each column of merchandise. Thevarious columns may be set at various prices. With pushbutton operationof my coin register, coins are first deposited and then a selected pushbutton operated.

My totalizer includes a change maker which receives a predeterminednumber of actuating impulses on each operation of the machine. Asolenoid actuated latch normally locks the change maker againstoperation by the actuating impulses. When a sum in coins in excess ofthe purchase price of a selected article has been deposited iu themachine, the selector and totalizer switches energize one of a number ofchange relay solenoid windings. Energization of a change relay windingmomentarily completes the drive motor circuit. As the drive motorrotates, it operates its follow-through switch to hold the motor circuitfor the remainder of the cycle of operation. The motor follow-throughswitch also completes through one of a plurality of interruptingswitches a holding circuit for the energized change relay winding, whichcompletes the circuit of the release solenoid for the change makerlatch. Energization of the change maker latch release solenoid permitsthe change maker to be operated by the actuating impulses. A motor drivecam opens the interrupting switch associated with the energized changerelay winding at a point in the operating cycle at which the correctamount in change has been made. The remainder of the operating cycletakes place in the same manner as that when no change is to be made. Mytotalizer is arranged to permit adjustment of the sale price of anyarticle in a rapid and expeditious manner. It includes means forinforming a customer that the supply of change in the change maker isexhausted. Reset means responsive to the delivery of an article ofmerchandise resets my coin totalizer circuit relays.

In the accompanying drawings which form part of the instantspecification and which are to be read in conjunction therewith and inwhich like reference numerals are used to indicate like parts in thevarious. views:

FIGURE 2 is a fragmentary elevation of the other side of myelectromechanical coin totalizer.

FIGURE 3 is a fragmentary end elevation, with parts broken away, of myelectromechanical coin totalizer.

FIGURE 4 is a fragmentary sectional elevation of the change marker of myelectromechanical coin totalizer.

FIGURE 5 is a sectional view of my electromechanical coin totalizer,taken along the line 55 of FIGURE 4.

FIGURE 6 is a schematic view of the electric circuit of myelectromechanical coin totalizer.

More particularly referirng now to FIGURE 1 of the drawings, my cointotalizer, indicated generally by the reference character 10, includes aflanged mounting plate 12 carrying projections 14 by means of which thetotalizer may conveniently be mounted in the machine with which it is tobe used. A coin separator and slug ejector, indicated generally by thereference character 16, may be of any type known to the art whichseparates nickels, dimes, and quarters deposited in the machine andwhich tests deposited coins and ejects spurious coins.

A pair of plates 18 and 20 supported by plate 12 and maintained inspaced relationship by appropriately shaped spacers 22 and 24 form adime coin passage indicated generally by the reference character 26. Thepath of a dime passing downwardly between plates 18 and 20 along thepath defined by spacers 22 and 24 is indicated by a dotted line inFIGURE 1. I mount a third plate 28 in spaced relation with plate 20 byappropriately shaped spacers 30, 32 and 34. Plates 20 and 28 togetherwith spacers 30, 32 and 34 define respective nickel and quarter coinpassages, indicated generally respectively by the reference characters36 and 38. For purposes of convenience, I have indicated the path of anickel passing downwardly between plates 20 and 28 along the pathdefined by spacers 30 and 32 by a broken line. The path of a quarterpassing downwardly between plates 20 and 23 along the path defined byspacers 32 and 34 is indicated by a dot-dash line. I mount the assemblyincluding plates 18, 20 and 28 and spacers 22, 24, 30, 32 and 34 onsupport plate 12 by any convenient means to position coin passages 26,36 and 38 to receive, respectively, dimes, nickels and quarters from theoutlet passages of separator and slug ejector 16.

To the left of plate 28, as viewed in FIGURE 1, plate 18 carries a pairof spaced guide members 40 and 4-2. Members 40 and 42 slidably supportrespective racks 44 and 46, retained in members 40 and 42 by a plate 48.Pairs of respective ears 52 and 54, one pair of which is shown, formedon plate 48, are secured to guides 40 and 42 by any convenient meanssuch as screws 56. Respective pins 58 and 60 carried by the lower endsof racks 44 and 46 as viewed in FIGURE 1 engage the lower edge of plate48 to limit the upward movement of racks 44 and 46 in a manner whichWill be described hereinafter. The upper ends of racks 44 and 46 maycarry respective pins 62 and 64 to limit the downward movement of theracks. Rack 44 is formed with a plurality of spaced escapement teeth 66along its outboard edge as viewed in FIGURE 1. Rack 46 is formed withescapement teeth 68 along its outboard edge. Adjacent escapement teeth68 are spaced apart a greater distance than are the teeth 66. As will beexplained in detail hereinafter, this spacing of the escapement teeth onthe respective racks is an analogue of value of coins adapted to spacethe rack.

Respective escapement mechanisms associated with racks 44 and 46 permitpredetermined movements of the racks downward under the influence ofgravity. I pivotally mount a first escapement latch 70 on a pin '72carried by a lug 74 formed on plate 48. Latch 70 includes respectiveupper and lower arms 76 and 78. I pivotally mount a second escapementlatch 80 on a pin 82 carried by a lug 84 formed on plate 48. Escapementlatch 80 includes respective upper and lower arms 86 and =88. Anelongated screw 90 passes through an opening in the lower end of latch80 and has its end threadably engaged with latch 70. A spring 92 carriedby the shank of screw 90 forces the lower ends of latches 70 and 80apart to pivot the respective latches so that upper latch portions 76and 86 engage the escapement rack teeth 66 and 68. This pivotal movementis limited by the engagement of head 94 of screw 90 with latch 80. Underthe influence of spring 92 the upper arms 76 and 86 of the respectiveescapement latches 70 and 80 respectively engage a tooth 66 of rack 44and a tooth 68 of rack 46. It will be seen that upper arms 76 and 86positioned by spring 92 restrain racks 44 and 46 from movement downwardunder the influence of gravity.

I provide means for pivoting or rotating the respective latches 70 and80 in response to the deposit in the totalizer of coins to permitpredetermined downward movements of racks 44 and 46 under the influenceof gravity. A screw 96 or the like secures a feeler 98 to latch 80 belowits pivot pin 82. A lateral projection 100 formed on feeler 98 extendsthrough an arcuate slot 102 in plate 28 into the quarter coin passage 38defined by plates 20 and 28 and spacers 32 and 34. A quarter passingdownward through passage 38 engages projection 100 to move feeler 98 torotate escapement latch 80 against the action of spring 92 in aclockwise direction as viewed in FIGURE 1. As the escapement latchpivots, arm 86 moves out of engagement with a tooth 68 to permit rack 46to feed downward under the influence of gravity. Arm 88 arrests movementof rack 46 by engaging the tooth 68 released by arm 86. After thequarter passes by the projection 100, spring 92 resets latch 80 and arm86 engages the tooth 68 following the one it released when feeler 98moved. It will be seen that a quarter passing downward through passage38 actuates latch 80 to permit a predetermined movement downward of rack46.

A pin 104- carried by plate 18 pivotally mounts a bell crank having arms106 and 108. Any convenient means such as a screw 110 secures a feeler112 to arm 106. 1 form feeler 112 with a lateral projection 114extending through an arcluate slot 116 in plate 28 into the nickel coinpassage 36 defined by plates 20 and 28 and spacers 30 and 32. A nickelpassing downward through passage 36 engages projection 114 to move arm112 to pivot the bell crank including arms 106 and 108 in a clockwisedirection as viewed in FIGURE 1. When the bell crank pivots, its arm 108engages arm 76 to pivot latch 70 in a counterclockwise direction asviewed in FIGURE 1. When latch 70 pivots, arm 76 releases a tooth 66 andrack 44 feeds downward under the influence of gravity. Arm 78 moves into engage an escapement tooth 66 to arrest the downward travel of therack 44. After the nickel passes projection 114, spring 92 resets latch70, and arm 76 engages the escapement tooth 66 following the one itreleased. It will be seen that passage of a nickel downward throughpassage 36 permits a predetermined movement of rack 44. I space adjacentteeth 68 by a distance five times the distance separating adjacent teeth66. It will be seen that a quarter permits rack 46 to move through fivetimes the distance through which a nickel permits rack 44 to move.

Projection 114 on feeler 112 extends through an opening in plate 20similar to opening 116 in plate 28 to extend into the dime coin passage26 defined by plates 18 and 20 and spacers 22 and 24. A dime passingdownward through passage 26 engages projection 114 to permit apredetermined movement downward of rack 44 in the same manner as did anickel passing downward through passage 36. Screw 110 mounts a secondfeeler 118 on arm 106 for movement with it. Feeler 118 is formed with alateral projection 120 extending through an arcuate opening 122 in plate28 and through similar arcuate openings in spacer 32 and in plate 20 toextend into the dime coin passage 26 formed by plates 18 and 20 andspacers 22 and 24. After a dime passes by projection 114 and latch 70and the associated bell crank return, the dime travels downward throughpassage 26 to engage projection 120 to pivot the bell crank includingarms 106 and 108 in a clockwise direction as viewed in FIGURE 1. Thisaction permits a second predetermined movement downward of rack 44.

It will be seen that passage of a nickel through coin passage 36 permitsa predetermined movement downward of rack 44. A dime passing throughpassage 26 permits twice the movement of rack 44 as did a nickel.Passage of a quarter through passage 38 permits a movement of rack 46which is five times the movement of rack 44 in response to the passageof a nickel through passage 36.

A pinion 124 pivotally mounted on a pin 126 carried by a bent link 128totalizers or aggregates the respective movements of racks 44 and 46. Idispose pinion 124 between racks 44 and 46 to be engaged by bothrespective gear teeth 129 and 131 formed on the racks. A lug 133 formedon plate 48 has a slot which slidably mounts link 128. It will be seenthat if either of the racks 44 or 46 moves downward as viewed in FIGURE1, it drives pinion 124 along the other rack to move pivot pin 126downward the same amount. After the deposit of a sum in coins in themachine to permit movement of respective racks 44 and 46, pivot pin 126has moved downward a distance corresponding to the sum of the coinsdeposited in the machine. The lower end of link 128, as viewed in FIGURE1, carries a pin 130 which extends through a slot 13-2 formed in plate12.

Referring now to FIGURES 2 and 3, pin 130 engages a recess 134 formed inthe lower end of a drive link 136 slidably mounted in a bracket 138secured to plate 12 by any convenient means such as welding or the like.As link 1128 moves downward as viewed in FIGURES l to 3, pin 130 driveslink 136 downward. Gear teeth 140 formed on link 136 engage the pinion142 of a totalizer switch, indicated generally by the referencecharacter 144. Screws 146 fix the contact plate 148 and cover plate 152of switch 144 on plate 12. A pin 150 pivotally carried by plate 152 andby side 12 carries pinion 142 and switch contact arm 154 for rotationwith it. Switch 144 includes a plurality of contacts 156 adapted to beengaged by contact ann 154. In the embodiment of my invention as shown,switch 144 includes eleven contacts corresponding respectively todeposits in the totalizer of from zero to fifty cents in five-centincrements.

Respective conductors 158 connect the contacts 156 corresponding todeposits of from five to fifty cents to terminals 160 of the electricalcircuit of my coin totalizer to be described in detail hereinafter. Inresponse to the deposit of coins in the totalizer, drive link 136positions switch arm 154 to complete electrical circuits to dispense aselected article of merchandise and to make change, if necessary, in amanner to be described.

Referring now to FIGURES 4 and 5, a support panel 162 of the machinewith which my totalizer is used carries, by any convenient means such aswelding or the like, a change maker slide support plate 164. A retainingplate 166 carried by panel 162 retains a change maker slide 168 on plate164. One end of slide 168 carries a pin 170 which rides in a slot 172formed in plate 166. A spring 174 fixed between pin 178 and a pin 176carried by panel 162 normally urges slide 168 for movement to the leftas viewed in FIGURE 4. An opening 178 in plate 166 supports a coin tube188 containing a supply of coins, such as nickels, for making change.Slide 168 is formed with an opening 184 for receiving a coin 182 fromtube 180 when the slide is in the full-line position shown in FIGURE 4.When slide 168 moves to the broken-line position shown in FIGURE 4,opening 184 registers with an opening 186 formed in plate 164 and thecoin 182 passes out of opening 184 through the opening 186 into a changedelivery chute, indicated generally by the reference character 188,formed by a bafile 190.

The change maker includes a latch 192 pivotally mounted on a pin 193carried by panel 162. One end of latch 192 passes through an opening 194in plate 166 to engage a notch or opening 196 in slide 168 to retain theslide in its full-line position against the action of spring 174. I fixa solenoid armature 198 to latch 192 for movement therewith. A solenoidwinding 200 is adapted to be energized through conductors 202 and 204 todraw armature 198 upward as viewed in FIGURE 4 to lift latch 192 out ofengagement with notch 196.

When a selection has been made and coins aggregating at least thepurchase price of a selected article have been deposited in thetotalizer, the totalizer electrical circuit, to be described in detailhereinafter, energizes a motor 206 mounted on a bracket 203 by anyconvenient means such as bolts 210. A key or the like 212 fixes a changemaker slide actuating wheel 214 on the shaft 216 of motor 266 forrotation with it. Wheel 214 includes teeth 218 adapted to engage theleft end of slide 168, as viewed in FIGURE 4, to move the slide to theright against the action of spring 174. Wheel 214 includes a number ofteeth 218 equal to the maximum number of coins which are to be given inchange on any individual operation of the machine. In the embodiment ofmy totalizer shown, a maximum of four coins in change are given. Beforean operation of my totalizer, wheel 214 is in the position shown. Ifchange is to be made, solenoid 200 is energized to lift latch 192 out ofopening 196. With the latch disengaged, as a tooth 218 of wheel 214passes by the left end of slide 168 as the wheel rotates in thedirection of the arrow in FIGURE 4, slide 168 moves to the left underthe influence of spring 174 to drop a coin 182 through opening 186 intochute 188. As wheel 214 continues to rotate, another tooth 218 engagesslide 168 to move it to the right, as viewed in FIGURE 4, against theaction of spring 174 to receive another coin in its opening 184. Ifsolenoid 200 is not energized at this time, latch 192 again falls intoopening 196 and no further change is given during the operation of themachine. If solenoid 2% remains energized, additional coins in change upto three coins are given in change to a customer. It will be appreciatedthat if a quarter is the largest denomination coin which can be receivedby the machine, the maximum amount of change which need be given is, forany deposit, four nickels, where the article sale price is a nickel.

Referring again to FIGURE 1, after having passed through the respectivecoin passages 36, 2 6, 38, nickels, dimes and quarters pass into anescrow bucket, indicated generally by the reference character 220, fixedto plate 12 by any convenient means such as screws 222. Bucket 220includes a base 224 retained in a position to close the bottom of bucket220 by a spring 226 fixed between a pin 228 on bucket 220 and a pin 2311on base plate 224. Base plate 224 is adapted to be pivoted about itsleft edge as viewed in FIGURE 1 to direct coins from the bucket into asuitable coin receptacle (not shown) of a type known to the art. Plate224 is adapted to be tilted about its right edge, as viewed in FIGURE 1,to direct coins contained in the bucket to a coin return chute in amanner known to the art. I form base plate 224 with an arm 232 pivotallyconnected by a pin 234 to a link 236. A pin 238 pivotally connects theend of link 236 remote from pin 234 to one end of a coin bucketactuating lever 240.

Referring now to FIGURES 1, 2, 4 and 5, a pin 242 mounts the hub 244 ofa crank plate 246 on shaft 216 for rotation with it. Plate 246 carries apin 248 which pivotally supports one end of a link 250, the other end ofwhich carries a pin 252 which engages the bifurcated upper end 254 of acoin dumping and reset arm 256 mounted on a fixed pivot (not shown). Aspacer 251 between link 25%) and plate 246 ensures that there issufficient clearance to permit link 251) to pass by the hub 244 of crankplate 246 as the plate rotates. Arrn 256 carries a first roller 258passing through an arcuate slot 260' in plate 12. As motor shaft 216rotates to drive crank plate 246, link 250 oscillates arm 256 to moveroller 258 to engage a cam surface 262 formed on the underside of lever240, as viewed in FIGURE 1. A pin 264 pivotally mounts lever 240 onplate 12. As roller 258 engages surface 262 it pivots lever 240 in aclockwise direction, as viewed in FIGURE 1, to drive link 236 to pivotbase plate 224 about its left end, as viewed in FIGURE 1, to directcoins in bucket 220 to a suitable receptacle.

As arm 256 pivots to the right as viewed in FIGURE 2, a second roller266 pivotally carried by the arm engages a cam surface 268 formed on theunderside of a reset lever 278 pivotally mounted on a pin 272 carried byplate 12. Engagement of roller 266 with surface 268 pivots lever 270 ina counterclockwise direction as viewed in FIGURE 2 to engage a leafspring 274 carried by lever 270 with pin to reset racks 44 and 46 andtotalizer switch arm 154.

The machine with which my totalizer is used includes a coin return rod276 mounted for vertical sliding movement on plate 12 by any convenientmeans not shown). A pin 278 pivotally connects rod 276 to an arm 280carried by a pin 282 on plate 12, Rod 276 carries a pin 284 which passesthrough a slot 286 in plate 12 to engage a slot 288 formed in a link 290pivotally connected by a pin 292 to the end of lever 240 remote from pin238. Coin return rod 276 is adapted to be freed in a manner to beexplained hereinafter when the supply of a particular article ofmerchandise is exhausted. Movement of the freed coin return roddownward, as viewed in FIGURE 2, carries pin 284 downward in slot 288 tocam link 290 slightly to the right, as w'ewed in FIGURE 1. Continuedmovement of pin 284 downward pivots lever 240 in a counterclockwisedirection, as viewed in FIGURE 1, to pivot base plate 224 about itsright edge, as viewed in FIGURE 1, to direct coins in bucket 220 to acoin return chute (not shown). Plate 12 carries, by means such as rivets294, a bracket 296 formed with stop means 298 which engage the lower endof link 290 to prevent a dishonest customer from actuating the coinbucket operating lever 240 by jarring the machine to return coins afterthe machine is conditioned to operate before the coins have beenaccepted. Operation of the freed coin return bar 276 cams link 290 clearof stop means 298.

Rod 276 pivotally supports a roller 300 for engaging a surface 302 oflever 270 as the rod moves downward. Engagement of roller 300 withsurface 302 pivots lever 270 to return racks 44 and 46 and totalizerswitch arm 154 when the coin return rod 276 is actuated.

Referring now to FIGURE 6, the electrical circuit of my totalizerincludes a pair of conductors 304 and 306 connected respectively toterminals 308 and 310 of a suitable source of electrical potential.Conductor 312 connects totalizer switch arm 154 to conductor 304. As hasbeen explained hereinabove, arm 154 is adapted to be actuated inresponse to the deposit of coins in the machine to engage one of therespective contacts 156 of the totalizer switch. As is also explainedhereinabove, respective conductors 158 connect contacts 156 torespective terminals 160. The machine with which my coin totalizer is tobe used may include a selector switch indicated generally by thereference character 314 including respective contact arms 316, 318, 320,322 and 326 ganged by suitable mechanical means indicated by referencecharacter 328. If three dilferent kinds or brands of articles are to bedispensed by the machine each selling at a diiferent price, a respectivegroup of three contacts 330, 332 and 334 is associated with each of thearms 316, 318, 320, 322 and 326. It will be seen that switch 314 hasthree positions and in any one of the positions each of the arms 316,318, 320, 322 and 326 engages a corresponding terminal 330, 332, or 334of its group.

We connect predetermined terminals of the groups associated with arms316, 318, 320 and 322 to the proper ones of terminals 160 to dispensethe articles of merchandise at a set price and to make change asrequired, in a manner which will be explained hereinafter. For purposesof convenience, I have designated the terminals 160 connected to therespective contacts 158 corresponding to the deposit in the totalizer offrom cents to 50 cents in S-cent increments by respective referencecharacters 160a to 160i. My totalizer also includes contacts 160k to16011 to which certain of the selector switch contacts are connected toprovide proper change circuits. The connection between the contacts 330,332, or 334 corresponding to the selector switch arms and terminals 160ato 16011 may be set for sale prices of from 5 cents to 50 cents in5-cent increments. The pattern of connections shown in FIGURE 6 isarranged to dispense an article of merchandise corresponding toterminals 330 at a price of cents. An article of merchandisecorresponding to terminals 332 is sold at a price of 10 cents. Anarticle of merchandise corresponding to terminals 334 is sold at a priceof cents. The proper connections for selling an article of merchandiseat various prices are shown in the following table:

Selector Switch Arm Price It will be understood that conductive leads336, 341, 344, 338, 346, 340 and 342 are provided with readilydetachable terminals so that they may be shifted to make contact withany of terminals a to 160m, inelusive. In accordance with the pattern ofconnections set forth in the table, a conductor 336 connects contact 330associated with arm 316 to terminal 1600. A conductor 338 connects thecontact 330 associated with arm 318 to terminal 160d. A conductor 340connects contact 330 associated with arm 320 to terminal 160l. Contact330 associated with arm 322 is left unconnected for this sale price ofthe article corresponding to terminals 330. Respective conductors 341and 342 connect contacts 332 corresponding to arms 316 and 320 toterminails 160k and 160m. Contacts 332 corresponding to arms 318 and 322are left unconnected. Respective conductors 344, 346 and 348 connect thecontacts 334 corresponding to switch arms 316, 318 and 322 to termirials160g, 160k, and 160m. The contact 334 associated with arm 320 is leftunconnected. Other various sale prices of from S-cent to SO-ccntincrements can be set for the various units of the machine in accordancewith the above table.

A conductor 350 connects the contact arm 316 of switch 314 to onecontact 352 of a motor follow-through switch including a contact arm 354connected by a conductor 356 to one terminal of motor 206. Conductor 306is connected to the other motor terminal. Arm 354 normally engagescontact 352. When a sum in coins corresponding to the purchase price ofan article of merchandise has been deposited in the totalizer, thecircuit of motor 206 is completed from terminal 308 through conductor304, through conductor 312, through the totalizer switch 144, throughselector switch arm 316, through conductor 350, through contact 352,through arm 354, through conductor 356, through motor 206 and throughconductor 306 to terminal 310. As soon as motor 206 begins to rotate, afollow-through cam 358 fixed on shaft 216 by means such as a set screw360 urges a cam follower 362 out of a recess 364 formed in cam 358. P01-lower 362 actuates a linkage 366 to force arm 354 out of engagement withcontact 352 and into engagement with a second contact 368. A conductor370 connects contact 368 to conductor 304 to maintain the circuit ofmotor 206 for a single rotation of shaft 216. This followthrough circuitis necessary since, as soon as motor 206 begins to rotate, it driveslink 250 to begin resetting the totalizer switch 144 to interrupt thecircuit through the totalizer switch. It is to be understood that when asum in coins equaling the purchase price of an article of merchandisehas been deposited in the totalizer, arm 154 engages the contact 156connected to the contact 160 to which the contact 330, 332, or 334corresponding to the selected article of merchandise is connected.

A set screw 370 mounts a second cam 372 on shaft 216 for rotation withit. A projection 374 on cam 372 actuates a follower 376 connected to aswitch arm 378 by a linkage 380. As shaft 216 rotates, cam 372 moves arm378 to engage a switch contact 382 connected by a conductor 384 to oneterminal of a dispensing relay winding 386. I connect the other terminalof winding 386 to conductor 306 by a conductor 388. A conductor 389connects arm 378 to conductor 304. Respective conductors 390 and 392connect a selector switch latch solenoid 394 in parallel with winding386. Solenoid 394 operates a selector switch latch (not shown) of a typeknown in the art to prevent a change of selection after a dispensingoperation has been initiated. Thus, a dishonest person cannot obtain twoarticles of merchandise during one operation of the machine. When cam372 closes switch 378 it completes the circuit of windings 386 and 394from terminal 308 through conductor 304; through conductor 389; throughcontact arm 378; through conductor 384; through parallel connectedwindings 386 and 394; through conductor 388; and through conductor 306to terminal 310. The momentary energization of winding 386 by theengagement of arm 378 with contact 382 actuates respective contact arms3% and 398 to engage contacts 400 and 402. A conductor 404 connects arm396 to conductor 304. Conductor 406 connects arm 398 to a contact arm408 of a reset switch normally in engagement with a contact 410connected to conductor 404. I connect contact 402 to the terminal ofwinding 386 to which conductor 384 is connected. It will be seen thatthe engagement of arm 338 with contact 402 completes a holding circuitfor windings 386 and 394 from terminal 308 through conductor 304;through conductor 404; through arm 408; through conductor 406; througharm 398; through windings 386 and 394 to conductor 388. Energization ofwinding 394 engages a contact arm 412 with a contact 414. A conductor416 connects arm 412 to contact 400. A conductor 418 connects contact414 to one terminal of each of the respective delivery solenoids 420,422 and 424 of the machine with which my totalizer is associated.Respective conductors 426, 428 and 430 connect solenoids 420, 422 and424 to respective contacts 432, 434 and 436 of empty switches includingcontact arms 438, 440 and 442 normally in engagement with the respectivecontacts 432, 434 and 436. Respective conductors 444, 446 and 448connect arms 438, 440 and 442 to the respective selector switch contacts330, .332 and 334 associated with selector switch arm 326, which isconnected by a conductor 450 to conductor 306. Energization of windings386 and 394 to engage respective arms 396 and 412 with contacts 400 and414 compietes the circuit of the delivery solenoid 420, 422, or 424corresponding to the selected kind of merchandise from terminal 308through conductor 304; through conductor 404; through arm 396; throughconductor 416; through arm 412; through conductor 418; through asolenoid 420, 422, or 424; through a conductor 426, 428, or 430; throughan arm 438, 440, or 442; through a conductor 444, 446, or 448; throughthe contact 330, 332, or 334 engaged by arm 326; through arm 326;through conductor 450; and through conductor 306 to terminal 310. It isto be understood that the solenoid 420, 422, or 424, which is energizedis determined by the position of switch arm 326 to engage one of thecontacts 330, 332, or 334. Arm 326 is positioned when a customer makeshis selection. Energization of a solenoid 420, 422, or 424 actuates adispensing mechanism (not shown) of any type known in the art to delivera selected article of merchandise to a customer. As the articledispensed passes down the machine delivery chute (not shown), itactuates arm 408 to move the arm out of engagement with contact 410 tointerrupt the holding circuit of winding 386 to permit arms 396, 398 and412 to reset.

The machine with which my totalizer is used includes means for informinga customer that the supply of merchandise of the kind he desires isexhausted. A conductor 452 connects one terminal of a signal lamp 454 toconductor 304. A conductor 456 connects the other terminal of signallamp 454 to contacts 458, 460

462 associated with respective switch arms 438, 440 and 442. If thesupply of a particular kind or brand of merchandise is exhausted, theassociated empty switch contact arm 438, 440, or 442 is movedmechanically in a manner known to the art out of engagement with itsrespective contact 432, 434, or 436 and into engagement with arespective contact 458, 460, or 462. This action prevents completion ofthe circuit of the associated delivery solenoid 420, 422, or 424 andcompletes the circuit of signal lamp 454 from terminal 308 throughconductor 304; through conductor 452; through lamp 454; throughconductor 456; through the operated contact arm 438, 440, or 442;through conductor 444, 446, or 448; through arm 326; through conductor450; and through conductor 306 to terminal 310. I connect a solenoid 464in parallel with lamp 454 to be energized to free the totalizer coinreturn mechanism when the supply of the selected article of merchandiseis exhausted.

When a sum in coins in excess of the purchase price of an article ofmerchandise has been deposited in the totalizer, the circuit of motor206 is completed through one of a plurality of respective change makingrelay windings 466, 468 and 470. A conductor 472 connects one terminalof winding 466 to selector switch contact arm 318. A conductor 474connects one terminal of winding 468 to terminal 1602; a conductor 476connects one terminal of winding 470 to terminal 160i. A conductor 478connects the other terminal of windings 466, 468 and 470 to a contact480 normally engaged by the contact arm 482 of a change tube emptyswitch. Arm 482 is connected to conductor 306. From Table I it can beseen that the contacts 330, 332 and 334 associated with arm 318 areshown connected to such predetermined ones of terminals 160a to 160 thatwinding 466 is energized when a sum exceeding by 5 cents the purchaseprice of a selected article has been deposited in the totalizer. Forexample, if the purchase price of an article is 5 cents, thecorresponding terminal 330, 332, or 334 associated with arm 318 isconnected to the terminal 16% which corresponds to the deposit of a dimein the totalizer. It will be obvious that where the sale price is, forexample, a dime, the corresponding terminal 330, 332, or 334 associatedwith arm 318 need not be connected to terminal .1600 since the occasionwould not arise for the giving of only a single nickel in change forthis sale price. In other words, no single coin exceeding this purchaseprice by only a nickel could be inserted in the totalizer. Where a sumin coins requiring a nickel in change has been deposited in thetotalizer, the circuit of winding 466 is complete from terminal 308through conductors 304 and 312, through arm 154, through a conductor 158and a terminal 160, through a conductor connected to the proper contact330, 332, or 334 associated with arm 318, through arm 318, throughconductor 472, through winding 466, through conductor 478, through arm482, and through conductor 306 to terminal 310. Energization of winding466 engages respective contact arms 484 and 486 with contacts 488 and490. A conductor 492 connects arm 484 to terminal 160k. A conductor 494connects terminal 160k to a contact 496 of an interrupting switchincluding an arm 498. A conductor 500 connects arm 498 to conductor 356.I connect contact 488 to conductor 472.

It will be remembered that upon the deposit in the totalizer of a sum incoins exceeding the purchase price of a selected article by 5 cents, acircuit is completed from terminal 308 to conductor 472. Energization ofwinding 466 to engage arm 484 with contact 488 completes the circuit ofmotor 206 from conductor 472 through arm 484; through conductor 492;through conductor 494; through arm 498; through conductors 500 and 356;through motor 206; and through conductor 306 to terminal 310.Energization of motor 206 permits completion of a delivery cycle 'in thesame manner as that described in connection with the deposit in thetotaland izer of a sum in coins equal to the purchase price of an 11article. It will be appreciated that engagement of arm 484 with contact488 bypasses the selector and totalizer switches to provide a holdingcircuit for relay winding 466.

A conductor 502 connects contact 490 to one terminal of the change slidelatch solenoid 200, the other terminal of which is connected by aconductor 504 to conductor 306. A conductor 506 connects arm 486 toconductor 304. As has been explained hereinabove, energization ofsolenoid 200 lifts latch 192 to permit wheel 214 to actuate slide 168 todispense coins in change from tube 180. If solenoid 200 remainsenergized for a complete revolution of shaft 216, four nickels in changeare given the customer. It will be remembered that winding 466 isenergized when only a single nickel in change is to be given. I providemeans for interrupting the circuit of winding 466 to de-energizesolenoid 200 after a single operation of slide 168. A set screw 508fixes a cam 510 on shaft 216 for rotation with it. A projection 512 oncam 510 actuates a follower 514 before shaft 216 completes a quarter ofone revolution to move arm 498 out of engagement with contact 496 tointerrupt the holding circuit for winding 466. This interruption permitsarm 486 to move out of engagement with contact 498 to interrupt thecircuit of latch solenoid 200. This permits only a single operation ofslide 168 to give one nickel in change.

Winding 468 is energized upon the deposit in the totalizer of a quarterby reason of the connection of winding 468 to terminal 160:: byconductor 474. Energization of winding 468 engages respective arms 516and 518 with contacts 520 and 522. A conductor 524 connects arm 518 toarm 320 of totalizer switch 314. Respective conductors 526 and 528connect contacts 530 and 532 of interrupter switches including arms 534and 536 to terminals 160! and 160m. As can be seen by reference to TableI, I connect the contacts 330, 332 and 334 associated with arm 320 tocertain of terminals i601, 1601, or 168m to connect one of theinterrupter switch arms 498, 534, or 536 in the holding circuit ofwinding 468 to give from one to three nickels in change. If four nickelsin change are to be returned, as, for example, on the deposit of aquarter, when a S-cent purchase price is set, I connect the contact 330,332, or 334 associated with arm 320 to terminal 16011. If the price ofthe article being dispensed is 15 cents, so that two nickels are to begiven in change, the terminal 330, 332, or 334 associated with arm 320is connected to terminal 1601. Energization of winding 468 engages arm518 with contact 522 to complete the circuit of motor 206 from terminal308 through conductor 384; through conductor 312; through arm 154;through conductor 474; through arm 518; through conductor 524; througharm 320; through a conductor, such as conductor 340, to terminal 160];through conductor 526; through arm 534; through conductor 500; throughccnductor 356; through motor 206; and through conductor 306 to terminal310. Engagement of arm 518 with contact 522 also completes the holdingcircuit for winding 468. Energization of winding 468 also engages arm516 with. contact 520 to complete the circuit of the change slide latchsolenoid 200. A set screw 538 fixes a cam 540 on shaft 216 for rotationwith it. A projection 542 on cam 540 actuates a follower 544 to move arm534 out of engagement with contact 530 to interrupt the holding circuitof winding 468 before shaft 216 completes a half revolution. This actionpermits wheel 214 to actuate slide 168 twice to deliver two nickels inchange. It will be remembered that when motor 206 begins to rotate, itcompletes its own followthrough circuit by moving arm 354 intoengagement with contact 368.

If a quarter has been deposited and three nickels in change are to begiven, the circuit of motor 206 is completed through the interruptingswitch including arm 536.

A set screw 546 mounts a cam 548 on shaft 216 for rotation with it. Aprojection 550 on cam 548 actuates a follower 552 to move arm 536 out ofengagement with contact 532 to interrupt the holding circuit of winding468 before shaft 216 completes three-quarters of a revolution. Thisaction permits slide 168 to deliver three nickels in change. If aquarter has been deposited in the totalizer and four nickels in changeare to be given, the circuit of motor 206 is initially completed througharm 518 and through a conductor 554 which connects terminal 16011 toconductor 356. This also provides the holding circuit for winding 468.It will be seen that the holding circuit of winding 468 in this case isnot interrupted during the revolution of shaft 216. Consequently, slide168 delivers four nickels in change. When motor 266 completes arevolution, follower 362 drops into recess 364 to open the motorcircuit.

When two quarters have been deposited in the totalizer, arm 154 engagesthe contact 156 connected to terminal to complete the circuit of changemaking relay winding 470 from terminal 308 through conductor 304;through conductor 312; through arm 154; through winding 470; through arm482; and through conductor 306 to terminal 310. Energization of winding470 engages respective arms 556 and 558 with contacts 560 and 562. Aconductor 564 connects arm 558 to selector switch arm 322.

As can be seen by reference to Table I, I connect the contacts 330, 332and 334 associated with arm 322 to certain ones of the terminals 160k to16011 to give from one to four nickels in change as required. If only asingle nickel is to be returned, relay winding 466 is energized in amanner described hereinabove. Energization of winding 470 also engagesarm 556 with contact 560 to energize solenoid 200. If two nickels are tobe given in change, the holding circuit for winding 470 is completedthrough the interrupting switch including arm 534. If three nickels inchange are to be given, the holding circuit of winding 470 is completedthrough the interrupting switch including arm 536. If four nickels inchange are to be given, the holding circuit for winding 470 is completedthrough conductor 554. After the initial energization of motor 206through one of the interrupting switches including respective arms 498,534 and 536 or through conductor 554, cam 358 forces arm 354 intoengagement with contact 368 to complete the holding circuit for motor206 for one revolution. Upon the deposit in the totalizer of any sum incoins in excess of the purchase price of an article to energize motor206 in the manner described, the delivery operation of the machine takesplace in the manner described hereinabove in connection with the depositin the totalizer of a sum in coins equal to the purchase price of thearticle.

I provide my totalizer with means for indicating to the customer thatthe supply of change is exhausted and that he should use exact change.Respective conductors 566 and 568 connect a signal lamp 570 between acontact 572 associated with arm 482 and conductor 304. When the supplyof coins such as nickels 182 in tube is exhausted, switch arm 482 pivotsto engage contact 572 to complete the circuit of signal lamp 570 fromconductor 304 through conductor 568; through the lamp 570; throughconductor 566; and through arm 482 to conductor 306. 1

In operation of my electromechanical coin totalizer, a customer depositsa sum in coins in the machine with which my totalizer is used. Coinseparator and slug ejector 16 delivers quarters, dimes and nickels intothe respective coin passages 38, 26 and 36. Passage of a quarterdownward through passage 38 actuates arm 98 to permit a predetermineddownward movement of rack 46 to drive pinion 124 downward as viewed inFIGURE 1. This action moves link 128 downward to permit drive link 136to move downward as viewed in FIGURE 2 to pivot ann 154 to engage thecontact 156 corresponding clockwise direction as viewed in to thedeposit of a quarter. Passage of a nickel downward through passage 36actuates arm 112 to permit a predetermined downward movement of rack 44.This movement permits drive link 136 to move to step arm 154 from onecontact 156 to the following contact in a FIGURE 2. Passage of a dimedownward through passage 26 moves arm 154 through a distance of twocontacts 156 in a clockwise direction as viewed in FIGURE 2. It will beseen that in response to the passage oi? coins downward through passages38, 26 and 36, arm 154 moves to engage a contact 156 corresponding tothe sum in coins passing through the passages.

In the selector switch arrangement shown, as soon as a sum in coinsequal to the purchase price of a selected article of merchandise hasbeen deposited, the circuit of motor 206 is completed through thetotalizer and selector switches 144 and 314 in the manner describedhereinabove. It will be understood by those skilled in the art that Imay interrupt the circuit by a push button so that the machine will notoperate until a push button has been actuated. As motor 206 rotates, cam358 engages arm 354 with contact 368 to complete the motor holdingcircuit. Upon continued rotation of shaft 216, cam 372 engages arm 378with contact 382 to complete the circuits of the relay windings 386 and394. Energization of windings 386 and 394 engages respective arms-396,398 and 412 with contacts 400, 402 and 414 to complete the circuit of adelivery solenoid 420, 422, or 424 corresponding to the selected kind ofmerchandise. The energized solenoid operates the delivery mechanism (notshown) of the machine with which my totalizer is used in a manner knownto the art. The delivered article of merchandise moves reset switch arm408 out of engagement with contact 410- to permit relay windings 386 and394 to reset. If the supply of a selected kind of merchandise isexahusted, the associated arm 438, 440, or 442 moves to! engage itscontact 458, 460, or 462 to complete the circuit of signal lamp 454 andof the coin return relay solenoid 464 to inform the customer and topermit him to actuate the coin return mechanism.

As shaft 216 rotates, it drives crank plate 246 to drive link 250 topivot arm 256 to the right as viewed in FIGURE 2. As arm 256 pivots,roller 266 engages surface 268 to pivot lever 270 to engage spring 274with pin 130 to return pinion 124 and racks 44 and 46. This action alsoreturns link 136 and switch arm 154 driven by the link. Movement of arm256 also engages roller 258 with surface 262' to pivot lever 240 to movebase plate 224 to permit coins in bucket 220 to pass to a suitablereceptacle (not shown).

If the customer wishes his money returned, as when the supply of theselected kind of merchandise is exhausted, he moves the freed coinreturn bar downward as viewed in FIGURE 2. Pin 284 carried by the linkoperates link 290 in a manner explained hereinabove to pivot lever 240to move base plate 224 to direct the money in bucket 220 to a coinreturn chute (not shown). Actuation of bar 276 to return coins engagesroller 300 with surface 302 of lever 270 to pivot the lever to resetracks 44 and 46 and switch arm 154.

If a selection is made and a coin or coins aggregating a sum exceedingthe purchase price of the selected article by cents have been depositedin the machine, a nickel in change must be given. Upon such a selectionand deposit, the circuit of change maker relay winding 466 is completethrough the totalizer and selector switches, through the Winding 466,and through the change tube empty switch including arm 482. Energizationof winding 466 momentarily completes the circuit of motor 206 throughthe interrupting switch including arm 498 and through switch arm 434.This circuit also comprises the holding circuit for winding 466 As motor206 starts to rotate, it engages the arm 354 with contact 368 tocomplete the motor follow-through circuit. The dispensing.

operation then takes place in the manner described in connection withthe deposit in the machine of a sum in coins equaling the purchase priceof a selected article. Energization of winding 466 also completes thecircuit of the change slide latch solenoid 200 through contact arm 486.Energization of winding 200 permits Wheel 214 to actuate slide 168 todeliver nickels in change. After a predetermined rotation of shaft 216cam 510 moves arm 498 out of engagement with contact 496 to open theholding circuit of winding 466 to permit arm 486 to move out ofengagement with contact 490 to open the circuit of winding 200. Cam 510engages arm 498 at a time to permit only a single nickel in change to bedelivered by slide 168.

If a quarter has been deposited in the machine, rack 46 moves pinion 124to position arm 154 to engage the contact 156 corresponding to thedeposit of a quarter in the machine. The only situations in which morethan a single nickel in change need be given are those in which either asingle quarter or two quarters have been deposited in the machine. Thatis, a customer having change of a quarter would not, for example deposit20 cents in the machine to obtain a l0-cent item so as to require twonickels in change. If a quarter has been deposited in the machine, thecircuit of winding 468 is completed through a correct one of theinterrupting switches including arms 498, 534 and 536 or throughconductor 554 to ensure that the correct change, which may be from oneto four nickels, is given the customer. As is explained hereinabove, theterminals 330, 332 and 334 associated with selector switch arm 330 areconnected to proper ones of the terminals 160k to 16011 to achieve thisresult. Energization of winding 468 momentarily completes the circuit ofdrive motor 206 to initiate a dispensing operation in the mannerdescribed hereinabove. The engagement of arm 518 with contact 522 alsocompletes a holding circuit for Winding 468 through one of theinterrupting switches including arms 498, 534 and 536, or throughconductor 554, if one, two, three or four nickels in change respectivelyare to be given. If two nickels are to be given, cam 540 interrupts theholding circuit of winding 468 azEter slide 168 has delivered twonickels. If three nickels are to be given, cam 548 interrupts theholding circuit of winding 468 after three nickels have been deliveredby slide 168. If four nickels are to be given, the holding circuitthrough conductor 554 is not interrupted. When the delivery operation iscomplete, the electrical and mechanical parts of my totalizer are resetin the manner described hereinabove.

If two quarters have been deposited in the machine, rack 46 drivespinion 124 to position arm 154 to engage the contact 156 correspondingto the deposit in the machine of 50 cents. This action completes thecircuit of switch relay winding 470 through the terminal 160i.Energization of winding 470 engages ar-m 558 to complete the circuit ofmotor 206 through arm 322 and through an appropriate one of theinterrupting switches including arms 498, 534 and 536 or throughconductor 554. This circuit also forms the holding circuit for winding470. A delivery operation of the machine then takes place in the mannerdescribed hereinabove. As has been explained, I connect the contacts330, 332 and 334 to respective ones of terminals 160k to 160n to connectthe proper one of the interrupting switches including arms 498, 534 and536 or conductor 554 into the holding circuit 470 in accordance with theamount of change which must be given to the customer.

Energization of winding 470 also completes the circuit of the changeslide latch solenoid 200 through arm 556. Energization of this solenoidpermits slide 168 to deliver the proper number of coins in change. Theoperation of the interrupting switches to open the holding circuit ofwinding 470 is the same as the operation to open the circuit of winding468.

In the event that the supply of a selected kind of merchandise isexhausted, the corresponding arm 438, 440, or 442 moves into engagementwith a contact 458, 460, or 462 to energize signal lamp 454 to informthe customer that the supply is exhausted. This action also energizessolenoid 464 to free the coin return mechanism.

If the supply of coins such as nickels 182 in tube 180 is exhausted, arm482 moves to engage contact 572 to energize lamp 570 to inform thecustomer that he should use the exact change necessary to make apurchase.

It is to be understood that while I have shown a form of my totalizerincluding only three different selections of merchandise, I may provideany desired number. Furthermore, while the form of my totalizer shownincludes prices of from cents to 50 cents in S-cent intervals, I mayarrange my circuit to provide any number of different prices. As hasbeen explained hereinabove, for the purposes of convenience, I have setmy circuit up to dispense three different kinds of articles ofmerchandise which sell at three diiferent respective prices. I have setthe sale price of the article of merchandise to which contacts 330correspond at 15 cents. The article of merchandise corresponding tocontacts 332 is set to sell at cents. The article of merchandisecorresponding to terminals 334 is set to sell at 35 cents. It is to beunderstood that these prices set up may readily be changed by changingthe connection between the groups of contacts 330, 332, 334 and theterminals 160a to 16011, in accordance with Table I.

It will be seen that I have accomplished the objects of my invention. Ihave provided an electromechanical coin totalizer which may be arrangedto sell a number of different kinds or brands of merchandise at variousrespective prices. My coin totalizer is extremely flexible in that theprice at which a particular article is sold may readily be changed. Mytotalizer is simple in construction and certain and reliable inoperation. My coin totalizer may be set up to sell an article ofmerchandise at a price of from 5 cents to 50 cents in S-cent increments.My totalizer automatically makes change up to four nickels.

It will be understood that certain features and subcombinations such asfall within the scope of my claims are of utility and may be employedwithout reference to other features and subcombinations. It is furtherobvious that various changes may be made in details within the scope ofmy claims without departing from the spirit of my invention. It is,therefore, to be understood that my invention is not to be limited tothe specific details shown and described.

Having thus described my invention, what I claim is:

1.
